how do i use a field value rather than its API name

We have a series of contract templates that our developers created for us a year ago. I can easily edit them, but this has stumped me. We have changed a couple of picklist values that are pulled from Salesforce. To avoid trouble I only changed the label of the value and not its API Name in Salesforce. However, the template seems to be pulling through the API Name. How do I get it to pull through the Label?
